[meta-webserver][PATCH] nginx: add default proxy_params

["André Draszik" <git@andred.net>]

From: André Draszik <andre.draszik@jci.com>

As per Debian packaging - to use it, see
    https://wiki.debian.org/Nginx/DirectoryStructure#Extra_Parameters

    This file is most commonly included when Nginx is acting
    as a reverse proxy:
        include /etc/nginx/proxy_params;
        proxy_pass http://localhost:8000;
